It is clamped at its lower end and subjected to three concentrated loads. Determine the normal stresses at points A, B, C and D.[5 marks] Q2. Construct the rotation matrix to rotate this state of stress to its principal planes using the method of cofactors 96 115 172 σ = 115 140 157[5 marks] 172 157 150 1
